5 Claims. I (Cl. 1613f5)- The invention relates to hinges, and has foran object the provision of a strong, durable. and

inexpensive'concealed door hinge adapted for use on. an automobile body,the construction be- 5 ing such as to minimize strains on the pintle, toavoid interference with weather flanges-on the door, and to reduceobstruction of the doorway when the door is open.

The invention further consists in the several featureshereinaftersetforth and more particularly defined by the annexed claims.

In the accompanying drawing, Fig. 1 is'a fragmentary elevation of anautomobile body embodying the hinge of the inventiomparts of the bodybeing broken away and parts being shown in section;

Fig. 2 is a sectional view thereof the line 2-2 of Fig. 1;

Fig. 3 is a sectional view thereof taken along the line"33 of Fig. 1,the door being shown in open position;

Fig. 4 is a sectional view taken along the line 4-4 of Fig. 4, the doorbeing in an intermediate position, and

Fig. 5 is a fragmentary sectional detail view of a stationary hingemember forming part of the hinge.

In this drawing, the numeral'lO designate a door post or jamb of anautomobile body, and 11 a door occupying a doorway 12 in the body. Thedoor post may be covered at its outerand inner sides by respectivepanels 13 and 14, and the door 11 may be similarly faced with outer andinner panels 15 and 16, respectively. The outer door panel 15 isprovided with a weather flange 17 which overlies the edge of the bodypanel 13 when the door is closed, as seen in Fig. 2.

The door is supported by two or more hinges embodying the invention, onebeing shown. The door post 10 has a cavity 18 formed therein to receivea stationary hinge member 19 which is provided with upper and lowerflanges 20 let into the door'post and 'secured thereto by screws 21.

45 The hinge member 19 includes spaced parallel cheeks 22"connected atportions remote from the flanges 20 by a wall 23 and forming therewith arecess 24 which opens at the doorway. ,The

wall 23 includes an angular portion 25 which at 50 its forward edge isprovided with a hinge knuckle 26 disposed centrally between the cheeks22.

A movable hinge member 27 has a curved hooked portion 28 provided withopposite parallel faces 29 slidably fitting between the cheeks 22 of thestationary hinge member. The hooked taken along portion 28 has a pair ofspaced hinge knuckles 30 which fit between the knuckle 26 and the cheeks22 and are secured thereto by a pintle 31. The pintle is arrangedbetween the open front of the hinge member 19 and the rear wall 25 ofthis 0 hinge member, and is close to the wall 25, so as to providerigidity and so that the knuckle 26 can be relatively short in radialdirection. The

hinge member 27 carries a flange 32 which is let into the door and issecured thereto by screws 5 3 3. The flange 32 may be extended, asindicated, to form part of a similar hinge member of an 7 adjacenthinge, not shown, tofacilitate alignment. The stationary hinge membersof the ad- .'iacent hingesmay be similarly connected.

When the door is closed the hinged edge of the door lis contiguous to orclosely adjacent the edge of the door post 10, and the weather flange 17lies close to the body panel 13. The inner edge of the hooked portion 28of the movable hinge member is provided with a nose 28- which enters arecess 34 formed in the wall 23 of the stationary hinge member. Theextreme opening movement of the door is limited, as seen in Fig.

3, by the engagement of the movable hinge member 27 with a pair of lugs35 projecting from the cheeks 22 into the recess 24. between the cheeks.In the open position of the door, the hinge memher 27 extends only asmall distance into the doorway and has no projections on which clothingwill catch, and the open door does not appreciably reduce the effectivewidth of the doorway. The recess 24 of the stationary hinge member issubstantially concealed by the hook member 29 of the open door.

The inner faces of the cheeks 22 are provided with aligned arcuategrooves or tracks 36 concentric with the axis of the pintle 31. Balls3'7 are loosely mounted in hemispherical pockets 38 formed in theopposite parallel faces 29 of the movable hinge member 27 and aremovably mounted in the tracks 36. Grooves 39 are formed on the innerfaces of the cheeks in communication with the grooves 36 to permit entryof the balls into the latter grooves when the hinge is assembled. Theentry grooves 39 preferably extend from the inner ends of the grooves36, as seen in Fig 3. The entry grooves may be omitted in someinstances, especially when the hinge is constructed of sheet metalstampings. If desired,

-, oil holes 40 may be formed in the flanges of the stationary hingemember to communicate with the grooves 36.,

As the door is swung, the movable hinge member 27 is supported to alarge extent on the balls 37 which roll or slide in the grooves ortracks 36. Movement of the hinge member 2'7 in a radial direction isresistedby the balls, thus relieving the pintle 31 of most of the radialload. When the door is closed, an inward pressure on the movable hingemember is resisted by the shoulder formed at the recess 34, engaged bythe nose 28 of this hinge member, thereby avoiding any tendency for theballs to shift into the entry grooves 39, and reducing radial thrust onthe pintle. A slight opening movement of the door is sufiicient to movethe balls out of register with the entry grooves. The construction ofthe hinge is such that the segmental ball track has a relatively largeradius without requiring an excessively wide and deep hinge, and asingle ball in the track will provide an effective anti-frictionbearing.

What I claim as new and desire to secure by Letters Patent is:

1. In a hinge, the combination of a pair of relatively movable hingemembers, one of which has spaced cheeks receiving therebetween the otherhinge member, a pintle connecting said hinge members, at least one ofsaid cheeks having an arcuate groove concentric with said pintle, a ballmovably mounted in said groove and movably seated in the other hingemember, there being a ball entry groovein said-cheek extending from saidarcuate groove, and there being a pair of co-operative abutments on saidhinge members remote from said pintle and engageable when said ball isat said entry groove to prevent shifting of the ball into said entrygroove and to reduce radial thrust on said pintle. J

2. In a-hinge, the combination of a pair of relatively movable hingemembers, one of which has spaced cheeks receiving therebetween the otherhinge member, a pintle connecting said hinge members, at least one ofsaid cheeks hav- 1 ing an arcuate groove concentric with said pintle,

and a ball movably seated insaid groove and movably seated in the otherhinge member, there being a pair of co-operative abutments on said hingemembers spaced from said pintle and engageable when the hinge is closedto reduce lateral thrusts on said ball and on said pintle.

3. In a hinge, the combination of a pair of relatively movable hingemembers one of which has spaced cheeks and the other of which has ahooked portion received between said spaced cheeks, a pintle connectingsaid spaced cheeks and the end of said hooked portion, at least one ofsaid cheeks having a segmental arcuate groove concentric with saidpintle, said pintle being arranged near one side edge of said check andsaid groove having a portion near the other side edge of said cheek, anda rollable member movabLv seated in said groove and in said hookedportion and resisting both axial and radial thrust on the hinge.

4. In ahinge, the combination of a hinge member having spaced cheeks anda wall integrally connecting said cheeks and forming therewith a recess,said recess having a front opening and said wall being spaced rearwardlyfromv said opening, a hinge knuckle formed on said wail within saidrecess, a second hinge member having a hooked portion extending intosaid recess and having terminal hinge'knuckles embracing saidfirst-named knuckle, and a pintle connecting said cheeks and saidseveral knuckles and disposed adjacent said cheek-connecting wall.

5. In a hinge, the combination of a hinge member having spaced cheeksand a wall integrally connecting said cheeks and forming therewith arecess, "said recess having a front opening and said wall being spacedrearwardly from said opening; a second hinge member having a hookedportion .extending into said recess, a pintle con necting said spacedcheeks and the end-of said hooked portion and arranged ad iacent saidwall, at least one of said cheeks having a segmental arcuate grooveconcentric with said pintle, and a rollable member movably seated insaid groove and in said hooked portion and resisting both axial andradial thrust on the hinge.
